Checked on the pages listed under Sources on 28 October 2026. Platforms change limits; the app you post in has the final say.

How it counts

Characters are counted the way you see them: an emoji with a skin tone is one character. The TikTok bar counts UTF-16 units, as TikTok's API does, so some emoji count as two there. The X bar uses X's weighted count: every link is 23, emoji are 2.

Hashtags are counted wherever they appear in the caption. Duplicates are flagged, since repeating a tag adds length and nothing else.

Worked example

A 140-character caption with three hashtags and one emoji.

Instagram: 2,060 characters left. TikTok: 2,059, because the emoji is 2 UTF-16 units.

X: about 141 weighted characters (the emoji counts 2), 139 left.

Instagram hashtags: 3 of 5.
